What a play ledger is
A play ledger is a plain record with one line for each session: the date, the money you put in, the money you took out and the minutes you played. The result of a session is taken out minus put in. A minus sign means you finished behind.
Why keep one? Memory is kind to the good nights and quiet about the rest. A ledger gives the honest total, in rupees, week by week. It is not a bet tracker. It does not record each round, follow odds or judge a strategy. It tracks sessions, because a session is how play is felt and paid for.
How to use it
- Add a session soon after it ends, while the figures are fresh. Fill in the date, put in, taken out and minutes. A rough figure for the minutes is fine. A short note is optional.
- Count money the same way every time. “Put in” is what you added for the session. “Taken out” is what you took back, or the balance you finished with if you prefer to count that way. Treat bonus money the same way each time too.
- Read the totals, the running-total line and the weekly and monthly tables under the form.
- Press Download CSV now and then. If you add a wrong entry, press Delete on its row, and Undo if you press it by mistake.
What the ledger works out
For every session it works out the result. Then it adds up the money in, the money out, the net, the average per session, the result for every hour played, how many sessions ended behind, and how many rupees came back for every ₹100 put in. Weeks run from Monday to Sunday, so each session falls in exactly one week. Money is added in whole paise, so a long ledger never drifts.
The page opens with an invented month so that you can see the shape. In it, 12 sessions put ₹7,200 in and took ₹6,095 out, so the ledger is ₹1,105 behind. ₹85 came back for every ₹100 put in. 9 of the 12 sessions ended behind and 3 ended ahead. By week and by month it looks like this:
| Week | Sessions | Put in | Taken out | Result |
|---|---|---|---|---|
| 7–13 Sep 2026 | 3 | ₹1,800 | ₹1,870 | +₹70 |
| 14–20 Sep 2026 | 3 | ₹1,700 | ₹1,250 | −₹450 |
| 21–27 Sep 2026 | 2 | ₹1,600 | ₹1,230 | −₹370 |
| 28 Sep – 4 Oct 2026 | 3 | ₹1,500 | ₹1,305 | −₹195 |
| 5–11 Oct 2026 | 1 | ₹600 | ₹440 | −₹160 |
| Month | Sessions | Put in | Taken out | Result |
|---|---|---|---|---|
| September 2026 | 9 | ₹5,400 | ₹4,530 | −₹870 |
| October 2026 | 3 | ₹1,800 | ₹1,565 | −₹235 |
These sessions are made up. They are nobody’s results and not a guide to what you will see.
Reading a ledger honestly
A ledger can look worse than the percentage a game states, and that is not a mistake. Suppose a game keeps 2% of every stake. You might expect ₹98 back for every ₹100 you put in. But the 2% applies to every stake, and the money you put in is staked again and again as you win and lose. Put ₹100 in and stake ₹1,000 over the session, and a 2% edge keeps ₹20 of it on average. ₹80 comes back, not ₹98. The session timer shows what a session of a given length and pace should cost on average, and your ledger shows what actually happened.
A short ledger also swings. In another invented ledger of ten sessions, the running total reaches +₹1,750 after three sessions, then slides to −₹2,650 by the tenth. A good start says little about the next session. In a third, one four-hour night accounts for −₹2,200 of a −₹2,610 total, so most of the loss came from a single session. A ledger shows both patterns more clearly than a feeling does. Set what it shows beside the average from the expected-loss calculator for your own stake and pace.
Where your entries live
Only in this browser, on this device, in the browser’s local storage. Nothing is uploaded, there is no account, and the page has no way to send your entries anywhere. That has three consequences. Another phone, another browser or a private window will not show them. Clearing your browser’s site data erases them, and some browsers, Safari on an iPhone among them, can clear a site’s saved data after about a week without a visit. So download a CSV as your own backup. And anyone who opens this page in this browser can see them, so press Clear everything before you lend your phone. The ledger holds up to 5,000 sessions.
What it cannot do
It cannot check what you type or see any account, so it is only as accurate as you are. It is not an accounting or tax record. It cannot sync between devices, and it cannot predict anything: a ledger describes the past. If the totals show more than you meant to spend, talk to someone you trust.

Common questions
Where is my play ledger stored?
Only in this browser, on this device, in the browser’s local storage. Nothing is uploaded and there is no account. Another phone, another browser or a private window will not show your sessions, and anyone who opens this page in this browser can see them.
What happens to my ledger if I clear my browser data?
It is erased. Clearing site data, or a browser that does so on its own, removes the saved sessions, and nothing can bring them back. Some browsers, Safari on an iPhone among them, can clear a site’s data after about a week without a visit. Download the CSV from time to time as a backup you keep yourself.
What do put in and taken out mean in the ledger?
Put in is the money you added for a session. Taken out is the money you took back when it ended, or the balance you finished with if you prefer to count it that way. Pick one rule and use it every time, because the result is simply taken out minus put in.
How do I open the CSV in Excel or Google Sheets?
Press Download CSV, then open the file in Excel, or in Google Sheets with File and then Import. The columns are date, put in, taken out, net, minutes and note. A note that starts with =, +, - or @ gets a quote mark in front, so a spreadsheet shows it as text.
Why do the weekly totals run from Monday to Sunday?
So every session lands in exactly one week and the weeks line up with the calendar on your phone. A week that crosses a month end, such as 28 September to 4 October, is one row in the weekly table and is split between two months in the monthly one.
Will keeping a ledger change how much I lose?
The ledger does not change the odds, and it does not claim to. It puts real numbers where memory is unreliable, because good nights are easy to remember and the rest are easy to forget. What you do with the numbers is up to you.
